[ Watch the Video: New Species Of Carnivorous Dinosaur Found In Utah ] Lawrence LeBlond for redOrbit.com - Your Universe Online Tyrannosaurus rex has long been considered the apex predator of its time. But this large meat-eating theropod’s earlier relatives did not celebrate such stature, based on new evidence by a multi-institutional team of researchers who have found a new contender to fill the role of top dog during the early-to-mid-Cretaceous period. Researchers from...

Alan McStravick for redOrbit.com - Your Universe Online The heaviest flying bird tops out at between 40-42 pounds. And sure, some of the flightless birds can grow to upwards of 300 pounds. But to imagine ancestors of these modern day creatures tipping the scales at upwards of 7,000 pounds is hard to do, indeed. A recent study out of North Carolina State University (NCSU) and the Field Museum in Chicago, Illinois, looks specifically at the feathered herbivores of the Cretaceous period...

While dinosaurs such as the Tyrannosaurus rex have long been assumed to be carnivorous, many of them were, in fact, vegetarians, according to a new study set to be published in the journal Proceedings of the National Academy of Sciences (PNAS). Paleontologists from the Field Museum in Chicago, Illinois, used statistical analysis in order to discern the dietary preferences of 90 species of theropods--bipedal, bird like dinosaurs that first appeared in the late Triassic period. Of those...

A new dinosaur species found in southern Utah has been identified, a fearsome looking creature that ate only plants, researchers say. Lindsay Zanno, a paleontologist at the Field Museum in Chicago, and her colleagues described Nothronychus graffami in a paper published Tuesday in Proceedings of the Royal Society B: Biological Sciences, the Chicago Sun-Times reported. The species is related to the velociraptor, the carnivorous dinosaurs made famous by the book and movie Jurassic Park, and to...

Scientists have caught a dinosaur in the act of evolving from meat-eater to vegetarian. The two-legged, feathered creature ate plants, but its bones show that the transition from its carnivorous ancestors was still in progress. All plant-eating dinosaurs were ultimately descended from a meat-eater, and switchovers to plant-eating occurred several times. The newly discovered species, which lived 125 million years ago in what is now Utah, could help scientists understand details of how the...
